Donald TrumpDonald TrumpTrump lawyers to Supreme Court: Jan. 6 committee 'will not be harmed by delay' Two House Democrats announce they won't seek reelection DiCaprio on climate change: 'Vote for people that are sane' MORE tweeted out his latest attack on MSNBC's "Morning Joe" co-host Mika Brzezinski on Friday, calling her “crazy and very dumb” and saying she had a breakdown on air.
Trump wrote on Twitter that he had heard that Brzezinski “had a mental breakdown while talking about me."
“Joe [Scarborough] a mess!” he added.
The “Morning Joe” hosts have been increasingly critical of the GOP presidential nominee in recent weeks.
Scarborough has repeatedly mocked Trump by calling him “Amnesty Don” when it was rumored that he would be mitigating his hard-line immigration stance. On Wednesday, Scarborough released a music video, singing of Trump's "premature softening" on the issue.
Trump has focused much of his return ire on Brzezinkski, tweeting last week that she was "a neurotic and not very bright mess!" He also implied a romantic relationship between Brzezinkski and Scarborough.
